I got my oil changed yesterday. What should have cost about $40 ended up costing me $155 because I let the guy talk me into additional services. it sounded like important maintenance things that needed to be done, so I told him to go for it.
When I got home, Tim told me that for $30 worth of parts and fluids he could have done the same thing. I got suckered.
Is it just me, or would you have known better?
